👉 An "antistadholderian" is a type of anti-gravity device that can be used to generate and sustain an artificial gravity field. These devices are designed for use in space exploration, especially in the context of asteroid mining or asteroid exploration missions. The concept of "antistadholderian" was first proposed by Soviet cosmonauts Mikhail Gorkin and Yuri Gagarin in 1960. They were able to generate a stable artificial gravity field using this device
